Polyhedral models, which are used in most graphics applications, require considerable amounts of storage, even when they only approximate precise shapes with limited accuracy. This course analyzed storage costs
for 3D shape representations and covered
several recent schemes for lossy and loss-less compression of triangle, polygonal, and
tetrahedral meshes. It reviewed both
single-resolution compression schemes
for triangle and polygonal meshes, which
result in compressed formats of less than
a byte per triangle, and multi-resolution progressive-refinement approaches.

Prerequisites
Some familiarity with basic concepts of meshes and standard representations of polygonal models.
